Definitions
- the present invention relates to the formation of an oligomeric organophosphoms composition (e.g., a phosphate or phosphonate) by the addition of a novel additive for the color improvement of the resulting product.
- an organophosphorus compound e.g., a pentavalent phosphorus ester
- phosphorus pentoxide e.g., phosphorus pentoxide
- alkylene oxide e.g., a reagent
- the final compositions include those containing phosphate and/or phosphonate moieties.
- Oligomeric organophosphorus compositions which may contain phosphate and/or phosphonate groups, optionally also containing hydroxyalkyl substitution, and which are made by the reaction of an organophosphorus compound, phosphorus pentoxide and an alkylene oxide (optionally with a reagent producing hydroxyalkyl substitution therein), can have their color improved by conducting such a reaction in the presence of an effective amount of a aryl group-containing phosphite, such as triphenyl phosphite.
- a aryl group-containing phosphite such as triphenyl phosphite.
- the initial reaction medium that is formed comprises a selected organophosphorus compound, such as a trialkyl phosphate or a dialkyl alkylphosphonate, with a selected amount of aryl group- containing phosphite (from about 0.01 wt% to about 5 wt%, based on the amount of organophosphorus compound).
- a selected organophosphorus compound such as a trialkyl phosphate or a dialkyl alkylphosphonate
- a selected amount of aryl group- containing phosphite from about 0.01 wt% to about 5 wt%, based on the amount of organophosphorus compound.
- phosphorus pentoxide is added to react with the selected organophosphorus compound followed by an additional amount of phosphite (from about 0.01 wt% to about 5 wt%, based on the weight of phosphorus pentoxide).
- the alkylene oxide e.g., ethylene oxide
- the selected aryl group- containing phosphite is used in an effective amount (from about 0.01 wt% to about 5 wt%, based on the amount of final product) to reduce the level of undesired color in the oligomeric product which is produced.
- the level of phosphite needed will, in general, increase as one increases the level of phosphorus pentoxide that is employed in the reaction.
- the aryl group- containing phosphite employed can be a monoaryl dialkyl phosphite, a diaryl monoalkyl phosphite, a triaryl phosphite, or mixtures thereof.
- both unsubstituted or substituted (e.g., alkyl substituted) alkyl or aryl groups can be employed.
- the alkyl group either base alkyl group or substituent can range from one to about ten carbon atoms in size.
- the preferred triaryl phosphite species for use is triphenyl phosphite.
- An example of another triaryl species is trinonylphenyl phosphite.
- the present invention is further illustrated by the Examples that follow.
- a reactor equipped with an agitator, thermometer, gas inlet, and reflux condenser was charged with 284 g of dimethyl methylphosphonate and 13 g of triethyl phosphite.
- the solution was warmed to 50°C, and 284 g of phosphorus pentoxide was added, with the exclusion of moisture and air.
- the slurry was then heated to 110°C until no further reaction was observed.
- 13 g of triethyl phosphite was again added to the reaction mixture.
- ethylene oxide was introduced into the reaction mixture until no further reaction was observed. This was indicated by a strong reflux of ethylene oxide on a dry ice condenser.
- This Example illustrates the prior art technology in the manufacture of a modified version of FYROL 51 flame retardant, in which ethylene glycol was not used and wherein a lower hydroxy content material was formed.
- a reactor equipped with an agitator, thermometer, gas inlet, and reflux condenser was charged with 409 g of dimethyl methylphosphonate and 7.6 g of triethyl phosphite.
- the solution was warmed to 50°C, and 260 g of phosphorus pentoxide was added, with the exclusion of moisture and air.
- the slurry was then heated to 85°C until no further reaction was observed.
- Ethylene oxide was then introduced into the reaction mixture until no further reaction was observed. This was indicated by a strong reflux of ethylene oxide on a dry ice condenser.
- Stannous octoate (1.8 g) was added to the reaction mixture, the temperature raised to 100°C and ethylene oxide addition continued until no further reaction was observed.
- This Example illustrates the prior art technology in the preparation of a poly(ethyl ethyleneoxy) phosphate composition.
- a reactor equipped with an agitator, thermometer, gas inlet, and reflux condenser was charged with 417 g of triethyl phosphate.
- the solution was warmed to 50°C, and 217 g of phosphorus pentoxide was added, with the exclusion of moisture and air.
- the slurry was then heated to 85°C until no further reaction was observed.
- Ethylene oxide was then introduced into the reaction mixture until no further reaction was observed. This was indicated by a strong reflux of ethylene oxide on a dry ice condenser.
- 1.2 g of stannous octoate was added to the reaction mixture, the temperature was raised to 100°C, and ethylene oxide addition continued until no further reaction was observed.
